Specification of Letters Patent.

Patented June 2, 1908.

Application filed May 31, 1907. semi No. 376,642.

To all whom it .may concem:

Be it known that I, DANIEL M. KENYON, a citizen of the United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented new and useful Improvements in A aratus for Coupling Pipe,of which the'fdlibwing is a specification.

My invention relates to apparatus for coupling pipe, and the object ofmy invention is to provi two sections of pipe to make their tubularportions continuous.

My invention consists in construcYtin a mechanical device designed toaccomp ish.

the assembling of pipe by inserting one ,sec-

tion or member withln the packing ring andpnlarged portion of anothermember or coup- My invention further consists in the various details ofconstruction and improvements hereinafter specifically described andclaimed.

Reference is hereby made to the accompanying drawing in which similarnumerals of designation refer to similar parts throughout the severalviews.

Figure 1 is a perspective view of my assembling apparatus showing theposition of the yokes, inserting implements, traversing nuts, and doublescrews before the pipes are put together. Fig. 2 is a view inperspective of my assembling apparatus showing its position upon thesections of have been put together. g. 3 is a View in pers ective ofthat portion of my apparatus whic is used for removing .the insertingslips after the pipes have been assembled. Fig. 4 is a cross section online 4-4 of Fig. 2 looking Fig. 5 is a showing the packing or gasket inits recess 'yoke;

Referring to the drawing, 9 is a tubular" after onesection of ipe hasbeen inserted within the other. F1g. 6 shows per ctive views of the longand short insert ng s ips respectively. Fig. 7 is an end elevation oftheremoval collar. Fig. 8 is a side elevation of the double screw.- Fig. 9is a side elevation of the single screw. ,Fig. 10 is a view in elevationof the yoke shown in Fig. 1. Fig. 11 is an'end elevation of amodification ofsaid pipesection having in one end thereof an'ene.aneffective means of uniting p]i5pe after the same largement or head 35(see 5), containing a recess 10 adapted to receive and retain an annularring of compressible packing 37', and to allow the introduction of theplain end of the pipe section 12 through the use of my im.- proved aparatus hereinafter described.

7 an 7 are inserting strips or implements each of w ich is preferablyformed with a-blade 57 esigned to be introduced into the interior of theenlargement 35', and to press outwardly on thepacking 37.

56 is an enlargement of the implement which forms am abutment'andprevents the slip from further enteringthe pipe;

8 is a fin er designed toiengagewith the exterior of tile head 35 and tohold the slip in position.

54 is a boss or flange'which' serves the purpose of providing a means bywhich the strip may be withdrawn after the two pipes have beenassembled.

13 and 14 are two oppositely arranged yokes having on each side thereofnut sockets 19 and 20 adapted to receive and retain traversing nuts 21and 23. i

27 and 28 are lugs containing the holes 29 dlingthe yokes an for bracingthe same, but are not essential to my invention and may be dispensedwith.

25 is a double screw, the opposite ends of which engage with thetraversing nuts 21 and 23. I have shown only two of these screws, butwhile I have found that these accomplish the objects of my inventionsatisfactorl I by no means desire to limit myself to the use of suchnumber, but may employ a larger umber of screws should occasion andcireumstance require. The ends 31,, 32 of the screws are squared so 'asto permit .the ready attachment of the. j acks- 33 and 34, each of whichcarries the ratchet and pawl 58.

36 are wedges which are introduced in the openings 61 betwe'en the innersurface of the yokes and the outer surface of the pipes: are screws adated to increase the effectiveness of said we to the art.-

7 and which is similar to the yokes shown in Figs. Land 2, and is wedgedaganistlon itudinal movement in the same manner.

is a yoke moving freely upon the pipe and a carries in each of itssockets 44 a swivel plate 46 in which is secured by a nut or rivet 47the screw stem 24 on the screw 42. are nut sockets containing nuts 22similar to those before' described. 52 are two hooks preferably integralwith the yoke 38 and adapted to recelve one of the middle links ofthechain 50, 51, which is secured at its opposite extremities to staples orhooks 48 and 49 on the removal collar. The removal collar is made in twoparts 15 and 16 as shown in Fig. 7, and is pivoted at 64.; their .upperextremities are secured together by means of the metal loop 17, which ispivotally mounted on part 15 and which engages with the metal tongue 18,and thus locks the collar. The said-collar is of such diameter that itcan readily surround the said implements T and 7 and at the same timeengage with the flanges 54.

40 and 41 are jacks similar to 33 arid 34 and each carry the rachet andpawl 59.

In Fig. 11 I have shown a modification of the yoke shown in Figs. 1, 2,3 and 10. It is made in two parts which are secured together by means ofthe lock oint 62 and pin 63. At the sides thereof are nut sockets 19similar to those before described.

The mode of operation of my apparatus is as follows :I first insert theimplements 7 and 7 so that the edges thereof shall overlap the adjacentedges of the implements in the manner shown in Fig. 4. I next place theyokes 13 and 14 upon the pipe and wedge the same securely againstlongitudinal movement. The traveisin nuts 21 and 23 are turned to theextremitles of the screw 25 and are installed in the boxes or sockets 19and 2.0. The jacks 33 and 34 are then' placed upon the square ends 31and 32, and are worked back and forth simultaneously until the pipe 12is gradually drawn within the slips 7 and 7 the'packing 37 is compressedinto the space between the pipes, and the two members duly installed. Toremove the inserting implements I employ the device shown in Fig. 3. Ifirst remove the yokes 13 and 14 together with their screws, nuts,jacks, etc. and upon the pipe.12 in a suitable position I lace the yoke39. On another ortion of t e pipe a little nearer to the strips placethe freely moving yoke 38, and over the inserting strips I lock the twoparts of the collar 15 and 161 Then by working the single screws 42 and43 by means of the jacks 40and 41, I gradually draw the insert- 1ng stris out of the joint. In some instances; prefer to employ the improvedyoke shown in Fig. 11. The construction of the lock joint 62 enables itto be readily installed while in thegditch, and the pin 63 securelyfastens the two portions of the same together. Upon driving the wedgesinto the openings 61 and adjusting the other parts of the apparatus, theyoke is ready for use. Where the packing ring is normally thicker thanthe special utility, as the amount of power employed is very great, andif necessary can be increased by using more screws or having them offiner thread. Thus I am enabled to apply great force with theexpenditure of but little effort, a factor which is of considerable.practical value where the pipes are put together in ditches or in otherplaces dil'licnlt of access.

Being simple in construction and composed of a number ofremovable partsmy apparatus can be readily broken down or put together simply bydisposing of the wedges and by lifting the traversing nuts'out of theirsockets, or dropping them in, so that with a number of workmen theseveral parts are easily transported and installed when they are workingon a line. My invention may also be utilized for pulling the twoportions of a pipe line together, where for any reason a section hasbeen forced out of its joint, as, for instance, on side hills orelsewhere where the sections are likely to sag and pull apart.

While I prefer to use a double screw as shown in Figs. 1 and 2, I by nomeans desire to limit myself to the use of this particular form ofscrew. For the sake of economy, the apparatus shown in Fig. 3 may beemployed for assembling the pipe as well as removing the insertingimplements. When used for the former urpose, the chain 50, 51 isdisconnected and yokes 38 and 39 are placed in the same relativepositions occupied by yokes 13 and 14 in Fig. 1, and wedged in the samemanner. By turning the screw in the opposite direction to that abovedescribed for removing the implements, the pipe sections will be drawntogether.

What I claim and desire to secure by Letters Patent is 1. In anapparatus for coupling two sections ofpipe the heads thereof containingrin s of compressible packing, yokes adapted to be secured to each ofsaid sections, combined with means for compressing said packing, andmeans for drawing said yokes towards each other and introducing theplain end of one of the sections within the packing ring 'in the head ofthe other while said packing is being compressed.
